Cubic Silicon Carbide Whiskersyog lub siab-lub zog hwj txwv-zoo li tus (ib-dimensional) monolithic, uas muaj ntau yam zoo heev txhua yam khoom xws li high-strength thiab high qauv.Nws yog dav siv nyob rau hauv cov hlau-raws li thiab ceramic-based composite cov ntaub ntawv.Nws yog tsuas yog siv nyob rau hauv high-temperature Cheebtsam nyob rau hauv lub tshav pob ntawm ceramics, lub teb ntawm qhov chaw, bearing, loj av nkos twj tso kua mis, thiab lwm yam.

Cov yam ntxwv ntawm lub cev: Nws yog hom cubic siv lead ua, uas yog tib hom siv lead ua zoo li pob zeb diamond.

Cov yam ntxwv tshuaj: tiv thaiv hnav, kub tsis kam, tshwj xeeb tshaj yog kub poob siab, corrosion kuj, hluav taws xob tsis kam.

Daim ntawv thov: high-end ceramic bearing, pwm, high-voltage firing, kub tsis kam, thiab lwm yam.

Silicon carbide muaj pob zeb diamond siv lead ua qauv.Qhov no yog vim cov pa roj carbon thiab silicon uas tsim SiCs.Lawv nyob rau SP keeb ntawm IVA nyob rau hauv lub caij voj voog lub rooj.Thaum cov ntsiab lus no tsim cov crystals Loj ruaj khov SP3 yog npaj, muaj cov khoom siv cov khoom siv, cov yam ntxwv ntawm tus nqi thiab siab zog ntawm tus yuam sij, txiav txim siab tias silicon carbide muaj qee lub zog thiab lub zog txhua yam.SIC's MOBS hardness mus txog 9.5, thib ob tsuas yog pob zeb diamond.Cubic SiC whiskers muaj hardness siab dua, modulus, tensile zog thiab kub tsis kam tshaj lwm yam khoom siv whiskers.

SiC whiskers muab sib npaug sib npaug hauv cov khoom siv lub cev ntom ntom raws li theem ob cov khoom, uas tuaj yeem phim lub cev zoo.Tom qab qhov kub thiab txias yog tsim, vim hais tias cov thermal expansion coefficient ntawm cov siv lead ua thiab cov khoom siv lub cev sib txawv, cov siv lead ua thiab cov khoom siv lub cev sib cuam tshuam Tom qab qhov kev ntxhov siab ntau dhau yog tsim, tom qab cov khoom sib xyaw yog me ntsis tawg, kev ntxhov siab ntawm qhov tawg. kawg txuas mus rau cov siv lead ua thiab matrix interface.Absorbing sab nraud kev nyuaj siab.Nyob rau hauv txoj kev no, SiC whiskers tuaj yeem tiv thaiv kev nthuav dav ntxiv ntawm micro-cracks los ntawm "bridge couplet", "crack deflection", "crystal rub tawm teebmeem" thiab "kev cuam tshuam siv lead ua tawg", yog li txhim kho thiab txhawb nqa lub cev ntawm lub cev.Cov khoom siv sib xyaw muaj siab toughness thiab mechanical zog.Vim tias SIC crystals yuav tsum muaj kev ruaj ntseg zoo ntawm qhov kub thiab txias, nws cov ntaub ntawv zoo dua qub thiab cov khoom sib xyaw ua ke tseem tuaj yeem tuav cov khoom zoo thaum 1000 ° C saum 1000 ° C.

Cubic Silicon Carbide Whiskerstuaj yeem siv los ua cov khoom siv kho kom zoo hauv cov yas matrix, hlau matrix lossis ceramic substrate los txhim kho thiab txhawb nqa.Cov kev taw qhia siab thermal, siab rwb thaiv tsev ntawm SIC cov ntaub ntawv, substrates rau loj-scale integrated circuits nyob rau hauv lub electronics kev lag luam thiab ntim cov ntaub ntawv.Raws li cov ntaub ntawv kho qhov muag, nws muaj txiaj ntsig zoo hauv kev ua haujlwm ntawm TV zaub, kev sib txuas lus niaj hnub, thiab kev sib txuas lus.

Carbonic silicon carbide whiskers yog cov khoom siv txhim khu kev qha zoo heev rau cov hlau, ceramic, thiab polymer polymer puag sib xyaw.
